Molybdenum is the ideal material for glass melting electrodes due to its good electrical and thermal conductivity, excellent corrosion and creep resistance. Generally, the diameter of electrode ranges from 10mm to 120mm, which is mainly depended on the current density.

To melt borosilicate glass, the most common diameter of electrode is 50mm. When the current density ranges between 0.42 A/cm2 and 0.49A/cm2, the electrodes do not need to be moved forward as they have no consumption. For vertical electrodes, whether the electrode to be continued in the furnace required to be evaluated when the density value reaches 0.8A/cm2.

For electric furnaces with a long furnace age (more than 4 years), the current density increases as the electrode is consumed. If the electrode is not ready to continue, the current density needs to be controlled at a lower value. Normally, there is little consumption for moly electrode when the current density runs below 0.6A/cm.

When molybdenum glass melting electrode is used to smelt soda lime glass and other low-resistance glasses that have a resistivity lower than 15Ω·cm, it is difficult to control the current density below 0.6A/cm2 because of its low viscosity and low resistivity. Therefore, electrodes with φ75mm diameter are often used. In addition, the electrodes will also have different degrees of loss during operation, so the electrodes must be made continuous. From the perspective of operating cost, the plate electrode consumes less and is more suitable for electrofusion of soda lime glass.

The conductive distance of the electrode has a direct impact on the service life of moly electrode. If the distance is too close, it will be in a low-voltage and high-current state during operation. This local high power will not only reduce the life of refractory materials, but also increase the electrode loss and bring defects to the product. In addition, if the current density value is too large, the destructive effect on the electrode will be even greater. Within the allowable range of voltage that the electric melting furnace Cemented Carbide Tips can withstand, the high-voltage and low-current operation scheme can improve efficiency on conditions that it must meet the requirements of melting process and operational safety.

It is reported on Nov. 27, that there is a Chinese molybdenum company wins the bid of buying Congo Freeport McMoRan's majority stakes, which has got the support and salutes from the government in Congo. The mine is a copper project despite objections from state miner Gecamines.

This is a challenge transaction after Gecamines last week and assertation a right of first order dealing at the International Court of Arbitration.

Chinese Molybdenum spends $2.65 billion deal for Freeport's 56 percent stake, agreed to in May, must respect the rights of Gecamines, which holds a 20 percent stake in Tenke, one of the world's largest copper mines. K10 tungsten carbide rod

Toronto-based Lundin Mining (LUN.TO) exercise its right of first order on Nov. 15 and it owns the remaining 24% stakes, after which Freeport says the sale to China Molybdenum will go through. Gecamines said last month it had submitted an offer to buy Freeport's stake without revealing any details. Freeport denies that Gecamines has a right of first offer.

Democratic Republic of Congo, which mined nearly 1 million tonnes of copper last year, is Africa's top producer of the metal and also extracts significant quantities of gold, diamonds, cobalt and tin.

It is because of large amount of the mines, conflict metals are issued mainly based on Democratic Republic of Congo, including tungsten, gold, titanium, and tin. Conflict minerals are mineral mines where armed conflict and human rights abuses occur and mostly in the eastern region of DRC.

74 of Mendeleev's Periodic Chart of the Elements is tungsten and symbol W, which has been one of conflict metal. Wolfram is its another name used mainly in Europe. It owns properties of high melting point, high boiling point, high density, high tungsten carbide burrs thermal conductivity, high electricity conductivity, ect. Molybdenum is also a refractory metal, which is similar to tungsten. The Chinese molybdenum company wins bid in Congo is mainly dealing with molybdenum in China.

China molybdenum price is in the upward trend on February 20, 2021 after the holiday of Spring Festival. Driven by the continuous rise in international molybdenum price, domestic molybdenum chemical companies have strong rised tungsten carbide cutting tools mentality.

At present, molybdenum concentrate price is above RMB 110,000/ton, molybdenum oxide price is advancing towards RMB 1,660/ton. However, affected by the end of the Spring Festival holiday, Cemented Carbide Inserts traders' enthusiasm for entering the market has not yet reached the best state, so the atmosphere of buying and selling in the market is not good.

In the news: in January, factory prices for industrial producers nationwide rose 0.3% year-on-year and 1.0% month-on-month; purchasing prices for industrial producers rose 0.9% year-on-year and 1.4% month-on-month, according to data from the National Bureau of Statistics.

Transition metal dichalcogenides (TMDs) are interesting for understanding the fundamental physics of two-dimensional (2D) materials as well as for applications to many emerging technologies, including spin electronics. Here, we report the discovery of long-range magnetic order below TM=40 and 100 K in bulk semiconducting TMDs 2H-MoTe2 and 2H-MoSe2, respectively, by means of muon spin rotation (μSR), scanning tunneling microscopy (STM), and density functional theory (DFT) calculations.

The μSR measurements show the presence of large and homogeneous internal magnetic fields at low temperatures in both compounds indicative of long-range magnetic order. DFT calculations show that this magnetism is promoted by the presence of defects in the tungsten carbide ball crystal. The STM measurements show that the vast majority of defects in these materials are metal vacancies and chalcogen-metal antisites, which are randomly distributed in the lattice at the subpercent level.

DFT indicates that the antisite defects are magnetic with a magnetic moment in the range of 0.9 to 2.8 μB. Further, we find that the magnetic order stabilized in 2H-MoTe2 and 2H-MoSe2 is highly sensitive to hydrostatic pressure. These observations establish 2H-MoTe2 and 2H-MoSe2 as a new class of magnetic semiconductors and open a path to studying the interplay of 2D physics and magnetism in these interesting semiconductors.

Transition metal dichalcogenides (TMDs), a family of two-dimensional (2D) layered materials like graphene, have been a subject of tremendous amounts of experimental and theoretical studies due to their exciting electronic and optoelectronic properties. TMDs share the same formula, MX2, where M is a transition metal and X is a chalcogen. They have a layered structure and crystallize in several polytypes, including 2H-, 1T-, 1T′-, and Td-type lattices. Much interest has focused on the cases of M=Mo or W, because the 2H forms of these compounds are semiconducting and can be mechanically exfoliated to a monolayer.

In bulk form, 2H-MoTe2 is a semiconductor with an indirect bandgap of 0.88 eV. The unique properties of TMDs especially in the monolayer form have shown great promise in device applications such as magnetoresistance and spintronics, high on/off ratio transistors, optoelectronics, valley optoelectronics, superconductors, and hydrogen storage. Many of these interesting properties arise on account of the strong spin-orbit interaction present in these materials due to the heavy metal ion.

While there are many studies focused on the spin-orbit coupling and the interesting consequences for electrical and optical properties in these systems, there are very limited, and mostly theoretical, studies on intrinsic magnetism in these materials. Theoretical and experimental work shows that in the absence of crystalline imperfections, the Mo-based TMDs are nonmagnetic. The ability to add magnetism into the properties of these materials can open up a host of new opportunities as tunable magnetic semiconductors.

The ammonium molybdate, ammonium heptamolvbdate and ferro molybdenum prices increased slightly under relatively active trading activity in the market. Under the increased demand from downstream and low inventories of raw materials, molybdenum concentrate enterprises keep firm offers.

In the ferro molybdenum market, steel mills are Yg6 Carbide Tips active in steel tenders but the supply of raw materials tungsten carbide burrs is tight, and thus ferro molybdenum in the spot market is hard to purchase. Prices in the molybdenum chemical and its products market increased slightly. Under strong rised mentality of upstream and the slightly increased enquiries from end customers, suppliers are reluctant to sell at low prices.
